ActiveMQ is part of our fundraising architecture. It stands between civicrm and our operational cluster running the Donation Gateway extension providing a new payment gateway.

It's currently living on silicon, a member of frack.eqiad.wmnet.

Software

Currently we're running ActiveMQ 5.9.0 for our installation. The software needs to be puppetized but in the interim is located in /usr/local/apache-activemq, symlinked to the current version. The configuration is located in /etc/activemq.conf.

Configuration

Config files

There are two important config files for ActiveMQ:

  • /usr/local/apache-activemq/conf/actibemq.xml - This contains the specific conncetion information for activemq (eg defining transportConncetors). This gets loaded by activemq by default when activemq is invoked.
  • /etc/activemq.conf - This contains some environment variables for activemq

Connectors

<transportConnector name="stomp" uri="stomp://0.0.0.0:61613?transport.closeAsync=false"/>

Start/Stop

/etc/init.d/activemq {start|stop}

note: if stop doesn't work then just killall java

Testing donation consumption

  1. Follow the steps above to pull up the web interface.
  2. Under the "Operations" column click "Send to" for the "test_donations" queue.
  3. Insert a test message and click send. (The message body will consist of a JSON string. You can check the logs to see examples.)
  4. ssh to aluminium (or wherever civicrm-dev is running from).
  5. cd to the /srv/org.wikimedia.civicrm-dev directory
  6. run "drush qc" to consume the queue
  7. If there are no errors, log into https://civicrm-dev.wikimedia.org/civicrm/ and look for the donation.
